Another type of steel, readily available in old saw blades, is L6. Look for an old crosscut saw (misery whip) or Sawzall blades. This is a high carbon steel with some nickel added. The heat treatment procedure for L6 is similar to that for 1095. L6 is slightly less hard and more t...
Because of the different compositions of these steels the hardness of the normalized steel varied though I was able to cut all of them with a bandsaw and drill a small hole. A very high hardenability steel like L6 or thinner steel like 1/16″ may air harden enough where bandsaw cutting ...
The chromium is for the purpose of “hardenability.” Hardenability is the measure of how slowly you can quench something and achieve full hardness. A steel with very high hardenability can be cooled in air from high temperature and fully harden. A low hardenability steel needs a water quench ...
(1)Galvanized steeltubesand carbon steel pipes with a nominal diameter less than or equal to 50mm are generally suitable for cutting with a pipe cutter; (2) High-pressuretubes andtubes with a tendency to harden should be cut by mechanical methods such as sawing machines and lathes. If oxya...
steel for decades. It is known for its fine carbide size and good toughness. The chromium addition compared with the chromium-free 1095 means that it hassomewhat higher hardenabilityso it is easier to harden in oil and obtain full hardness. The chromium also helps keep the carbide size small...
That helps when quenching in fast oil like Parks 50 rather than water to avoid warping and cracking. A similar steel to 26C3 is also shown in that hardenability article. 26C3 is not a true “oil hardening” steel so it needs a fast oil to fully harden, similar to a steel like 1095....
